    <description descriptionType="Abstract">&lt;p&gt;Correlations between mean transverse momentum $\left[{p}_{T}\right]$ and anisotropic flow coefficients ${v}_{2}$ or ${v}_{3}$ are measured as a function of centrality in Pb–Pb and Xe–Xe collisions at $\sqrt{{s}_{\mathrm{NN}}}=5.02$ TeV and 5.44 TeV, respectively, with ALICE. In addition, the recently proposed higher-order correlation between $\left[{p}_{T}\right]$, ${v}_{2}$, and ${v}_{3}$ is measured for the first time, which shows an anticorrelation for the presented centrality ranges. These measurements are compared with hydrodynamic calculations using IP-Glasma and ${T}_{R}\mathrm{ENTo}$ initial-state shapes, the former based on the Color Glass Condensate effective theory with gluon saturation, and the latter a parameterized model with nucleons as the relevant degrees of freedom. The data are better described by the IP-Glasma rather than the ${T}_{R}\mathrm{ENTo}$ based calculations. In particular, Trajectum and JETSCAPE predictions, both based on the ${T}_{R}\mathrm{ENTo}$ initial state model but with different parameter settings, fail to describe the measurements. As the correlations between $\left[{p}_{T}\right]$ and ${v}_{n}$ are mainly driven by the correlations of the size and the shape of the system in the initial state, these new studies pave a novel way to characterize the initial state and help pin down the uncertainty of the extracted properties of the quark–gluon plasma recreated in relativistic heavy-ion collisions.&lt;/p&gt;</description>
